METAL BILGE-BABREL.

Specification of Letters Patent.

Application led July 27, 1912. Serial No. 711,799.`

Patented May 26, 1914.

To all whom it may concern.'

Be it known that we, HENRY W. AvpRY and WALLACE S. JUDD, citizens of theUnited States, and residents of Cleveland, in the county of Cuyahoga andState of Ohio, have invented a certain new and useful Improvement inMetal Bilge-Barrels, of which the following is a full, clear, and exactdescription. c

This invention relates to metal bilge barrels and especially to certainnovel features of construction at the end portions of the barrels, or atthe chimes and junction of the heads with the barrel body.

The object of our invention is to provide a construction which is strongand able to resist all shocks and blows to which the end of the barrelmay or is liable to be subjected in use, without opening the seam at thejunction of the head and barrel.

Our invention may be briefly summarized as consisting in certain noveldetails of construction vwhich will be described in the specificationand set forth in the appended claims.

The single ligure of the drawings is a side' elevation of a barrelconstructed in accordance with the preferred form of our invention,parts being broken away and parts being in section.

The barrel includesa body A which is provided with a bilge and ispreferably composed of two half sections joined along their longitudinaledges, and each formed from a fiat sheet of metal. To strengthen thebody, the latter may be provided at the center with a circumferentialband B, which is pressed. or inset groove or corrugation of suitablewidth and depth. The body is closed at its ends by two metal heads Cwhich, together with certain features of construction at the ends of-the body form the principal parts of our invention.

A metallic barrel to answer the requirements imposed by the'trade musthave certain characteristics which include, of course,

' strength and rigidity at all points; the barrel must have a bilge andchimes to facilitate the handling of the barrel; and the barrel must beable to withstand severe tests, which consist usually in dropping thebarrel when filled with heavy liquid a certain distance onto the chimewithout opening a seam between thehead and body, or without springing aleak. This last test is required if the tion of gasolene, oils-Vor otherhighly iniammable-liquids, leakage of which would have a considerableelement of danger, as

well as result in loss of material. The bar-- rel which we have providedhas proven by test to answer all these re uirements.

Referring again to the rawing, it will be seen that the body A nearleach end has a barrels are to be used for the transportadepressed orinwardly offset portion a which extends circumferentially about thelbody at each end. The extreme ends of the offset portion a are curvedor rounded inwardly, as shown at a?. Each head C has a main centralportion which is convex outwardly and the head is provided near itsperiphery with a groove or annular troughlike portion c formed bybending metal outwardly as shown at c1, thence laterally as shown atlc2, and thence inwardly, as shown at c3, the latter constituting a angelike portion which extends beyond the body or main portion of the head.The head is fitted tightly onto the end of the barrel, the outer portionc3 overlapping the inset portion a yof the body, and occupying theannular depression formed by insetting this portion. The portion a isinset to a suitable depth so that when the head is in place, the portionc3 of the head is substantially flush with the barrel body, thusleavingat the ends no lateral projections. The end of the portion c3 extends tothe shoulder formed at the base of the inwardly offset portion a, andthe inwardly curved ends al ofthe offset portions a bear against thebase of the groove in the annular recessed portion c ofthe head, theportion a1 of the body and the base of the portion o of the head beingsimilarly curved, so that parts will fit closely together, and conformin curvature. After the head is placed in position in the mannerdescribed, solder may be run about the joint formed at the point ai.

The chief advantages of the construction above described are as follows:By providing an annular recessed or inwardly oifset portion at the endof the body, and by having the annular outer flange-like portion of thehead lit into the recess thus formed, and by having the edge of the headsubstantially engaging the shoulder formed at the base of the offsetportion a, and the end a1 of the offset portion aA overlapping andbearing against the base of the annular groove formed in the head, theend o f the barrel is given great strength, and when the chime issubjected to a heavy blow, such as results.

from the dropping of the filled barrel from a height, instead of theseam being opened, the stresses are transmitted along the barrel body,due largely to the peculiar inner {it ting and abutting portions of thehead and body at the chime.

Having thus described our invention, what we claim is:

l. In a metal barrel, a bilged body, heads fitted onto and secured tothe body, the body inwardly, and heads fitted onto and secured to theends of the body, each head having near its periphery an outwardlyoffset inwardly facing trough-like portion with an outer annular flangelike portion which is Iitted onto the inwardly oset portion of the bodyand extends to the shoulder at the base of said oset portion, and theinwardly bent ends of said offset portion of the body bearing againstthe base of the groove formed in the head-by said trough-like portion soas to strengthen the latter.

3. In a metal barrel, a bilged body having at its ends annular inwardlyoffset portions, the eXtreme ends of which are rounded inwardly, andheads fitted onto and permanently secured to ,the ends of the body, eachhead'having near its periphery an outwardly odset inwardly facingtrough-like portion forming a chime, the base of the groove formedthereby being rounded, the outer flange-like wall of said groove beingfitted onto the oiiset portion of the body, and its outer surface beingsubstantially iush with the surface of the body beyond said offsetportion, and the inwardly curved portion of the offset portion of thebody bearing against the base of the trough-like portion of the head soas to strengthen the v latter.

In testimony whereof, we hereunto afiix our signatures 1n the presenceof two witnesses.
